You can upload new firmware via a serial port connection to the Zipit's flash memory from a Windows PC or Linux box. First you have to modify your Zipit to add a serial port. See Zipit Serial Mod

To begin, perform the following instructions.

//If someone would like to add instructions for Linux in addition to Windows, it would be greatly appreciated.

What you need:

1.) Extract the Zipit software tools to a convenient location. 2.) Connect your modded Zipit to your computer through the serial port. Make sure that the debug pin (DBG) is grounded. 3.) In your extracted folder, open the folder named SERIAL_5. 4.) Run the file named up.bat. You should see the following below:

Transferring bootstrap program
Transfer complete
Switch to 57.6kbps
Echo + upload commands
       Decide what to upload
       'A' - allrom.bin upload (2MB)
       'a' - loader.bin upload (8K max)
       'k' - zimage.dat upload (581K max)
       'u' - ramdisk.gz upload (1.5MB max)
       Follow changes with 'WYes' to write
       Other commands
       'R' - grab ROM

ZP< .02 - 57.6Kbps new cmds
 Loader addresses: 00002000 00090000

OK >

5.) Now you need to type a lowercase "a" and press enter. You should see the text below.

OK > a
//Uploading 8032 bytes from loader.bin
// done upload
OK >

6.) Type in a lowercase "k" and press enter. This step may take a few minutes.

OK > k
//Uploading 573300 bytes from zimage.dat
// done upload
OK >

7.) Type in a lowercase "u" and press enter. This step may take quite a while, SO LET IT WORK! In my own personal experiences, it has taken 7 to 12 minutes.

OK > u
//Uploading 1372343 bytes from ramdisk.gz
// done upload
OK >

8.) Then, you need to type a capital "W". Wait a few moments until 'PWD' shows up, then type 'Yes', with the capital Y.

OK > [type W, wait for PWD, then type YES]
OK >

9.) Finally, type a question mark, and press enter.

OK > ?
GPIO: 80 FF 28 02

Congratulations, your Zipit now has Linux!
